    Hello Joseph

    Your team will need to review the Design Considerations and weight up whether your design solution is the most appropriate for this context https://ewbchallenge.org/challenge/saibai-island-tsirc/design-considerations/

    If you still think that tidal energy is a path worth exploring for design opportunity 4.1, here are some useful points to help your team research and further develop your idea

    Candidate zones for tidal-stream devices
    Only a few kilometres south of PNG, Saibai Island sits in the northern Torres Strait, where Coral Sea and Gulf tides collide, driving fast, predictable currents and a 3–4 m spring range.

    A Eastern approach (Saibai’s north-east coast)
    – Situated outside the main shipping lanes (but will require maritime safety markers).
    – Strong, consistent bi-direction flow

    B Saibai–Dauan Island channel
    – Narrow gap could create Venturi effect
    – Short length for sea cables?

    C North-west shore (Saibai–PNG coast)
    – Consider silt/sedimentation from PNGs rivers and ongoing maintenance, proximity to the township

    Other factors
    – What about impact to marine life (dugongs, turtles and fish)?
    – The TSRA Renewable Energy Transition Plan 2021 stresses community-led design and Indigenous employment pathways
    – Consider seabed, environmental assessment (acoustics, sedimentation, scour, exclusion zones etc)

    Hope this helps!
